Benefits of technology

[0119] The aerosol-deliverable formulation of the invention can provide a combination of the benefits of liquid abrasive cleaners, such as excellent cleaning of tough dirt, with th

Problems solved by technology

Disadvantages associated with current liquid abrasive cleaning compositions include the fact that they are not easily applied to and will not cling to vertical surfaces.
Further, they are not perceived to work without intensive rubbing/scouring and, as a result, they are associated by the consumer with a requirement for hard work.
In addition, current l

Example

Example 1

[0129] Three 75 ml aluminium Lechner aerosol cans were filled in conventional manner with the formulations below and were fitted with D.P.V. 841 valves. In particular, the required amount of liquid abrasive cleaner was put into the aerosol can. Air was then flushed out of the can with the propellant gas. The valve was then crimped on the can. After that, the required amount of propellant gas was injected into the can through the valve. The can was shaken to homogenise and emulsify the contents.

[0130] The spraying effect was recorded using various commercially available aerosol actuators and details are given below.

Example

Example 3

[0135] The formulations from Example 2 were stability tested in glass and tin aerosol cans at −10° C., 4° C., room temperature and 37° C. for 6, 8 and 12 weeks. During the evaluation points at 0, 6, 8 and 12 weeks, the cans were evaluated on various aspects, shaken to redisperse the calcite, sprayed and returned to storage. The following observations were made:

[0136] Appearance

[0137] Formulation 1 generally showed 4 layers in the glass aerosol can: from bottom to top classified as calcite sediment / cloudy / white / clear. Formulation 2 was nearly homogeneous at RT and 37° C. with a thin clear layer on top.

[0138] Dispersability

[0139] Formulation 1 generally needed serious shaking to redisperse the calcite in the formulation, whereas Formulation 2 (being more homogeneous) did not need shaking for the RT and 37° C. samples.

[0140] Weight Loss During Storage

[0141] No weight loss during storage was observed.

Abstract

An aerosol-deliverable formulation comprises a liquid abrasive composition having a viscosity of 1000 mPas or less, and a propellant. The formulation provides effective, and unexpected, suspensions of abrasives that do not settle from the suspension to form a hard cake of non-redispersible solid material.

Description

FIELD OF THE INVENTION [0001] This invention relates to aerosol-deliverable formulations, i.e. formulations that can be delivered in the form of an aerosol spray, foam or mousse from a pressurised container containing a propellant gas under pressure. The invention concerns aerosol-deliverable formulations comprising liquid abrasive compositions. BACKGROUND TO THE INVENTION [0002] Liquid abrasive compositions, particularly liquid abrasive cleaning compositions such as household cleaners, are well known and can be very effective in cleaning from hard surfaces tough stubborn soils, greases, burnt-in materials and stains which are often not completely removed by abrasive-free products. [0003] Typically, liquid abrasive cleaning compositions comprise suspensions of small particles of abrasive material, such as calcite, silica, magnesium silicate or the like in an aqueous phase comprising water, with optional surfactants and / or polymers to provide physical stability and surfactancy proper...
